Seagate Demonstrates HDD with PCIe NVMe Interface

Seagate has demonstrated the industry's first hard disk drive connected to a host using a PCIe interface at the Open Compute Project Summit. Like solid-state drives, the experimental hard drive uses the NVMe protocol to operate alongside SSDs seamlessly. Usage of a single protocol for different types of storage devices will greatly simplify datacenters.

The experimental [HDD] is based on Seagate's proprietary controller that supports all three major protocols, including SAS, SATA, and NVMe over a 'native NVMe port,' and does not require any bridges.

[...] Modern HDDs can barely saturate even a single PCIe 2.0 link, but future multi-actuator HDDs promise to be much faster, so 6 Gbps provided by SATA or 12 Gbps offered by SAS might not be enough at some point. To that end, the industry has to think about future interfaces to connect hard drives, and PCIe seems like a natural choice. Furthermore, as SSDs are gaining traction in datacenters, the NVMe protocol becomes pervasive, so it makes sense to adopt it for HDDs. This is why NVMe 2.0 adds hard drive support.

    So, is this drive a traditional platter drive, and SSD, or some kind of hybrid with a proprietary connector?

    It's an HDD. I replaced the typo just now.

    I simply can't imagine that the platters will ever equal the various memory chips already out there, with or without an acuator.

    They already got a 2-actuator 14 TB drive to 524 MB/s. Increase the capacity to the 30-100 TB range that is expected with heat/microwave-assisted magnetic recording (HAMR/MAMR), and double the actuators to 4, and 12 Gb/s SAS would not be enough.

    Obviously, the point is not to equal SSDs. Those can reach absurd speeds like 26,000 MB/s [wccftech.com] or a lot more as NAND density increases in the coming years.

    HAH! You didn't fix the typo at https://www.tomshardware.com/news/seagate-demonstrates-hdd-with-pcie-nvme-interface [tomshardware.com]
